GAS-PRODUCER.

Specification of Letters Patent. Application filed May 2, 1914. Serial in. 835,878.

Patented Nov. 3, 1914.

To all whom it may concern:

Be it known that I, CLAUDE M. GARLAND, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Gas-Producers, of which the 1 following is a specification.

My invention relates to producers of the mechanically operated type in which either a portion of the fuel chamber revolves or the ash supporting device revolves.

The object of my improvements is to provide a producer in which relative motion between the ash support andthe chamber is used to saw up and break up the clinker which has formed and also to tend to prevent the formation of clinker. This I accomplish by mounting saw teeth on the ash supporting device and either rotating this device or the chamber of the producer. The ash and fuel contained in the chamber will ordinarily cling to the chamber and either rotate with this or remain stationary with the chamber as the case may be. The saw teeth saw through the clinker which has formed and at the same time cause a twisting action to be produced in the ash bed and in the lower portion of the fuel bed which tends to maintain the bed unishown. The chamber 1 terminates in the bosh ring 13 which carries an annular rack 9 and a track 18 which is carried. on the rollers 10, supported by the columns 11.

3 indicates a stepped ash supporting structure mounted on the beams 4 which are supported from the shell 7 of the chamher 2.

8 is a water seal which prevents the escape of the blast admitted to the chamber 2,

through the blast connection 17. The

chamber 2 tapers to an openin about 18 inches indiameter, which is c osed by a valve not shown. The bosh ring 13 is pro vlded with projections 12 which project out into the ash and tend to cause this ash to rotate with the chamber 1.

5 indicates an ash bar supported from the shell 7, in the bushing 6. As the chamber 1 rotates the ash which tends to rotate with it is raked from the table 19 by the stationary bar 5. On the stepped structure 3 are mounted saw teeth 14. These teeth are preferably mounted at an inclination of about 45 to the vertical and are also preferably .made undulatory, that is, the cutting edge of the teeth are not contained in a horizontal plane. In the stepped structure 3 are located blast ports 15 through which the blast admitted at 17 passes to the center of the fuel bed.

In the operation of the producer the chamber 1 is rotated either continuously or intermittently through the rack 9. This causes the ash and fuel in the chamber to rotate also. As the stepped chamber 8 is stationary the clinker contained in the ash bin is slowly drawn over the undulating edges of the saw teeth which gradually cut the clinker into small pieces so that it descends on to the table 19 and from this table it is raked off by the ash bar 5 into the ash chamber 2.

The ash support 3 has been shown stepped in the drawing which is the preferred arrangement. This structure could bemade conical. It is also immaterial as to whether the chamber rotates and the ash supporting structure remains stationary or whether the ash supporting structure rotates and the chamber remains stationary.

Having thus described my invention I olaim- I 1. In a gas producer, an ash supportin table, a stepped structure rigidly mounted on the said table, a shell or chamber, saw teeth mounted on the steps of the said stepped structure and the said chamber adapted to rotate relative to the said ash supporting table,and the said stepped structure."

2. In a gas producer, an ash supporting table, a stepped structure rigidly mounted on the said table, saw teeth mounted on the steps of the said stepped structure, the edge of the said saw teeth forming an unthe said chamber adapted to rotate relatively to the said table.

4. In a gas producer, a chamber, projections carried by the said chamber for the purpose of causing the ash carried in the said chamber to remain stationary therewith, an ash supporting table mounted in the base of the said chamber, a stepped structure rigidly mounted on the said table, undulating saw teeth mounted on the steps of the said stepped structure, and the said chamber adapted to rotate with respect to thesaid ash supporting table.

5. In a gas producer, a chamber, projections carried by the said chamber, an ash supporting table, a stepped structure rigidly mounted on the said ash supporting table, ports for the admission of blasts in the said stepped structure, undulating saw teeth mounted on the steps of the said stepped structure, an ash bar extending over the said ash su porting table for the removal of ash, and 't e said chamber mounted rotatably with respect to the said ash supporting table, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesse.
